Neon signs are often placed in storefronts to attract customers. The very first display of glass tubes filled with colorful, ignited neon gas was meant to attract only attention, however. In 1910 at the Paris Exposition, two straight tubes filled with lit neon gas were displayed to show off the new technology. It was not until 1912 that glass tubes were bent into a written message and put in the window of a barber shop to entice people to come in.
We can infer that the reason the glass tubes were bent was that
- A. the Paris Exposition display was considered unsatisfactory
- B. straight tubes are not as bright as bent ones
- C. it is difficult to form letters with straight tubes
- D. neon gas burns out quickly in straight tubes
Correct Answer & Rationale
Correct Answer: C
The bending of glass tubes is primarily linked to the ability to form letters and shapes, making option C the most logical choice. Bent tubes allow for the creation of recognizable letters, essential for signage. Option A suggests the display's quality influenced the design, but it lacks direct relevance to the functionality of the tubes. Option B implies that brightness is affected by the shape of the tubes, which is misleading; brightness is more about gas type and tube diameter than shape. Option D inaccurately claims that neon gas burns out quickly in straight tubes; gas longevity is not dependent on tube shape but rather on electrical conditions and gas quality.

The passage is mainly discussing the Mississippi River's
- A. depth
- B. length
- C. width
- D. location
Correct Answer & Rationale
Correct Answer: C
The passage primarily focuses on the Mississippi River's width, detailing its varying measurements at different points along its course. This emphasis on width highlights its significance in navigation and ecology. Option A, depth, is not the main topic; while depth may be mentioned, it does not receive the same level of attention. Option B, length, is also a lesser focus, as the passage does not delve into the river's overall distance. Option D, location, is addressed but serves more as context rather than the central theme. Thus, width emerges as the key aspect discussed in the passage.

The retired government official spoke_______ about foreign policy and international trade.
- A. as knowing
- B. in knowledge
- C. knowledgeably
- D. knowledgeable
Correct Answer & Rationale
Correct Answer: C
Option C, "knowledgeably," is the appropriate choice as it is an adverb that describes how the retired government official spoke, indicating that he did so with knowledge and expertise. Option A, "as knowing," is grammatically incorrect in this context; it does not fit the structure of the sentence. Option B, "in knowledge," is awkward and does not function as an adverb, failing to appropriately modify the verb "spoke." Option D, "knowledgeable," is an adjective and does not correctly modify the verb, making it unsuitable for this sentence structure.
